B'eit that I, SPorrswoon' C. FosfrER, ac tizen of the United States, residing at Fredericksburg,-in the county of spottsyle ania and Stateof irginia, have invented new and .useful -Irnprove'nientsv lnG'overnors,

' of which the following is a specification.-

an electrical devic This invention is a governor for. waterwheels. or other .motors, and is particularly adapted for those used for generating electricity and operates to'vary the water-gate orother controlling-valve of the motor. The-il'ivention is adapted for operation by p e controlled according to .theload on the generator. and also by a mechamcal devicelaccording to the speed.

of part of'the apparatus; Fig. 3 is an end elevation; Figs. 4 and 5 are details in elevationand section of the connections between the governor and thespeed-regulating mech- Referring s dicates a pul ey' driven from the turbine-or motor shaft, and this -"with' the wheel and also in driving-contact with 'afriction cone-Wheel 18, the chance ter'of which at the middle is the same as that of the wheel10. The wheel 18 is fast upon a shaft 18","which also carries a bevel-gear 17.

The'bevel-gear 11 mesheswith a bevelg ar 12, whichhas a hub 12, and the bevelgear 17' meshes with a bevel-gear 16, which has a hub 16. These wheels 12 and 16 are loose upon a shaft or axle Also loosely mounted upon the shaft 22, between the hubs '12 'and.1-6 are bevel-gears 13 and 15, which havehubs (13 and 15 infrictional eontact at with the respective hubs 12 and 16 The diameter of these hubs or frictiers-surfaces is exactly the same at both places. The gears 13 and 15' both inesh'with a hevel- ,ear 14 upon a perpendicular shaft 19; whic may be connected in any suitable Manner to the water-gate of the turbine or to the. contro ling-valve of any other kind of rnotonshaft 22, between the'gears 1 and 15, serves to hold the gears in proper position and sup is thus driven.

its other end to a' ecifically to the drawings, 9 iii-- pulley is fast upon a .shaftfifl'which also carries a wide-faced friction-wheel 10 and a bevel-gear 11.

. friction at t A Spacing angleslecve on the evel-gear' 12 also meshes with the drivinggear 2010f the mechariicalgovrnor 23, which The friction-wheel 5 is loosely mounted upon a shaft 5",which is fixed in boxes 7 and '8 at the opposite-ends of a curved or semicircula'r yoke 40fwhfich is ivoted at 42 to a suitable supporting-brim et to swing in a transverse vertical plane, so that the wheel 5 mayrun up and down the conical Wheel 18.- A fork 4 is pivotally connected at the ends of its branches by loose in a circular h f h b 1 groove 6 around thehub 5 O t ewee 5.

This fork is connected at vertical I lever 3, which is fulcrumed at 3 on a standard 2 and has at its lower end alaterally-extending arm or pin 41. The lower end ofthe lever is also con--' nected' to the core 1" of a solenoid 1, which is in circuit with the translatingdevices or load. The lower end of'the lever 3 is also connected to a spring 24, which opposes the pull of the solenoid.

The sleeve of the mechanical governor is connected by a stud60 and link 60 'to one arm of a bent lever 25, which is fulcrumed at 26 to the governor-casing and is connected at its other arm to one end of a horizontallye ged over the e lower end of the lever 3. r

- Operation: The parts are so constructed that when the water-wheel is running at proper speed the friction-Wheel .5 is at the middle of the cone wheel 18, where said conewheel is. the sanie size as the friction-wheel 10, and consequently the gears 12 and 16 turn 'with e ual speed, and by the uniform The faces 50 the gears 13 and 15 have the samei force applied thereto, and consequently do not move, being in mesh with the gear 19, which accordingly does not aprvot-pin' 6 to a collar 6,-

'8: extending rod 21, the otherend of which has 4 a hook 21*, adapted to be engla laterally-extending pin-41 at t move. If the turbine or water wheel runs too slow, the governor '23 (which is driven by the gear 12) forces down the'sleeve 60 and link 60*, which turns the bent lever 25, and by means of the connecting-rodZI the lever 3 is swung, so that the fork 4 shifts-the wheel 5v toward the small end of the cone, said wheel being kept intzontaot by the swing 'of the yoke 40; This action increases the speed of the gear 16 ,"a'nd hence causes increased friction on that side, which thus drives the gear 15 with greate ifg force than the gear 13 and 'I5 wheel-5 to be pulled to the smell and of the tent', 11h

In its application to an electrical" iilent the rod 21 is disconnected; and the solenoid 1 is connected to the 'bus-bars of the plant.-

Should' the load rise; the strength of the solenoid-coil is weakened, allowing-the core 1 to be pulled out by the sp'rin 24th an extent inproportion to-the rise of. t e load, thereby swinging the: lever 8 and causing the frictioneone.
